本世纪70年代以来发展了一类新型化学电源,就是以锂做负极的各种锂电池。锂电池优于其他电化学系统,它的比能量高、比容量高,储存寿命长。有些锂电池如Li—SO_2电池,Li—SOCl_2电池,不仅比能量高、可大功率放电且放电温度范围宽(-50℃～+60℃),因而得到各国军方的重视和大力支持。本文介绍了各种材料作正极的锂原电池的组成,电池反应,优缺点及适用领域。
Since the 1970s, a new type of chemical power supply has been developed, that is, various lithium batteries made of lithium as a negative electrode. Lithium battery is superior to other electrochemical systems, its high specific energy, high specific capacity, long storage life. Some lithium batteries, such as Li-SO 2 batteries and Li-SOCl 2 batteries, not only have high specific energy but also discharge at high power with a wide discharge temperature range (-50 ℃ ~ + 60 ℃). Therefore, they have received great attention and support from various countries. This article describes the composition of a variety of lithium batteries for the positive electrode, battery reaction, advantages and disadvantages and application areas.
